Why it Matters
Interstate 15 is eastern Idaho’s primary north-south commercial corridor that serves interstate truck traffic, recreational vehicles and general traffic between Pocatello and the Utah border. An average of more than 15,000 vehicles traveled the route daily in 2008. Major improvements include pavement rehabilitation and bridge deck rehabilitation and repairs of some bridge substructures
Separate pavement rehabilitation projects, to be bid as one project, were planned for northbound and southbound lanes of Interstate 15 as part of the federal stimulus program. More than an inch of the existing surface will be milled and replaced by a durable four-inch “Superpave” overlay. The pavement project begins near the north end of Malad Summit and extends approximately five miles to the Downey Interchange.
In addition to pavement resurfacing, the project included rehabilitation of four bridge decks – Marsh Valley Road overpass; Woodland Road; Cherry Creek Bridge and Marsh Creek Bridge. Existing concrete slab approaches will be replaced on several bridges.
The northbound bridge deck at the Downey Interchange was replaced. Some minor repairs are planned on all bridge substructures, and approximately 9,500 feet of guardrail will replaced to bring them up to current height requirements. A weigh-in-motion facility near Browning’s Corner will receive new sensors and a new surface.
The project was planned for Fiscal Year 2012 but was advanced in the Statewide Transportation Improvement Program with the availability of federal stimulus funds.
